Data Sufficiency — find the lightest among five people Persons: P, Q, R, S, T. Statements: I. R is heavier than Q and T but lighter than S. II. S is not the heaviest. Choose the correct sufficiency option.

Difficulty: Easy

I alone is sufficient while II alone is not sufficient
II alone is sufficient while I alone is not sufficient
Either I or II is sufficient
Neither I nor II is sufficient

Correct Answer: Neither I nor II is sufficient

Explanation:

From Statement I
Order known: S > R > (Q, T). P is unplaced ⇒ lightest could be Q/T or even P ⇒ insufficient.

From Statement II
“S is not the heaviest” gives no relative info about others ⇒ insufficient.

Even together
We still cannot decide among Q, T, or possibly P for the lightest.

Answer
Neither I nor II is sufficient.
